List of BMS communication protocols.

[Piet_de _Pad]

Hi
Can someone provide me with a list of most used communication protocols used by a BMS to communicate with and inverter. I don't need the physical layer hardware protocols like RS485 or CAN. I'm looking for the level 2 layer where the exchange of data frames happen. The ones I have found are these.
DALY BMS protocol
Pylontech protocols
LUX protocol
MODBus
Are there more I'm not aware of?

Here are a few BMS protocols not on your list:

Seplos
Growatt
SMA
Victron
JK

Not all of these talk to the inverter directly.

Seplos doesn't have it's own protocol perse.
They reverse engineered the pylontech 1.3, and is fully compatible with pylontech 1 and 1.3

Don't know if PACE is a separate protocol but it is documented as such (somewhat).
The EG4/Narada protocol also has some documentation.

Thanks, I will add it to the list

Thanks for your input I will add this protocol to the list
